At ValidExamDumps, we consistently monitor updates to the IBM C1000-156 exam questions by IBM. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the IBM Security QRadar SIEM V7.5 Administration exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by IBM in their IBM C1000-156 exam. These outdated questions lead to customers failing their IBM Security QRadar SIEM V7.5 Administration exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the IBM C1000-156 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You are using the command line interface (CLI) and need to fix a storage issue. What command do you use to verify disk usage levels?
To verify disk usage levels in a Linux environment, the df -h command is used. This command provides an overview of the disk space usage, displaying the available and used space in a human-readable format.
Open the terminal or CLI on the system.
Type df -h and press Enter.
Review the output, which will show the filesystem, size, used space, available space, and usage percentage for all mounted filesystems.

What is the REST API interface to install and manage applications that are created by using the GUI Application Framework Software Development Kit?
The primary method used by IBM QRadar to install and manage applications created using the GUI Application Framework Software Development Kit (SDK) is through the REST API interface:
API Endpoint: /api/gui_app_framework
Functionality: This endpoint allows administrators to manage the lifecycle of applications, including installation, updates, and removal.
Integration: Provides seamless integration with the GUI Application Framework, enabling the development and deployment of custom applications within QRadar.
Reference The IBM QRadar API documentation provides details on the /api/gui_app_framework endpoint and its usage for managing GUI applications.
What is the default day and time setting for when QRadar generates weekly reports?
In IBM QRadar SIEM V7.5, the default setting for generating weekly reports is configured to occur on:
Day: Sunday
This setting ensures that the reports are generated during a typical low-activity period, minimizing the impact on system performance and ensuring that the latest data from the previous week is included.
Reference The default configuration for report generation times is specified in the IBM QRadar SIEM V7.5 administration and user documentation.
When creating an identity exclusion search, what time range do you select?
When creating an identity exclusion search in IBM QRadar SIEM V7.5, the time range selected is 'Real time (streaming).' This setting ensures that the search continuously monitors and excludes identities in real-time as data is ingested. Here's the process:
Real-time Monitoring: Continuously updates the search results based on incoming data, providing immediate exclusion of specified identities.
Streaming Data: Processes data in a live stream, ensuring that the exclusion criteria are applied instantaneously as new events occur.
Reference The setup and configuration of identity exclusion searches are detailed in the QRadar SIEM administration guides, highlighting the importance of real-time streaming for effective identity management.
What Iwo things are required for an administrator to deobfuscate data in QRadar?
In IBM QRadar SIEM V7.5, to deobfuscate data, an administrator requires two critical components:
Private Key: This key is used to decrypt the data that was originally obfuscated. The private key must match the public key used during the obfuscation process.
Password for the Private Key: This password is necessary to unlock the private key, allowing the decryption process to proceed.
The process involves using the private key in conjunction with its password to reverse the obfuscation, ensuring that the data is securely accessed only by authorized personnel.
Reference The requirement for the private key and its password for deobfuscating data is detailed in the IBM QRadar SIEM administration and security guides, ensuring that the process adheres to best practices for data security.
